T0 allwhom t may concern.'

Be it known that I, GILBERT L. IIUFF, a citizen of the United States of America, residing at the city of Holdenville, county of Hughes, State of Oklahoma,'have invented a certain new and useful Vending-Machine, of which the following is ksuch a full, clear, and exact description as willenable any one skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part ofV this specification.

My invention relates toa vending ma# chine, for vending thin articles, such as sheets of paper. rIhe object of my invention is to provide a device of the class described,

which will be simple and effective inoperation and which will dispense but a single article at a time. A Y

In the accompanying drawings, which illustrate one form of 'device made in accordancewith my invention, Figure 1 is a front elevation; Fig. 2 isa side view;A Fig.

3 is an enlarged horizontal section-through a portion of my machine; Fig. 4 is a section taken on the line 4 4 of Fig. 3; Fig. 5 is a section taken on the line 5-5 of Fig. 6; Fig; 6 is a section taken on the line 6 6 of Fig. 5.

10 represents the back portion of' the casing which is secured in vertical position by any suitable means, as for instance, the

openings 11, shown in Fig. 5 of the drawings. 12 is the front portion of the casing,

which is pivoted at its upper end to the rear portion 10 by means of hinges 13. The lower portion of the part 12 is secured to the member 10 by a lock 14. 15 represents a support for the articles to be vended. The support 15 is secured to the part 10 of the casing by means of hinges 16. Arranged between the hinges 16 is a coil spring 17 (Fig. 1), which is adapted to throw the lower end of the support 15 forward, the object of which will be hereinafter more fully described. Sheets of paper 18 rest in the support 15, and are prevented from falling downwardly by means of pins 19 carried by said support 15 and passing through suitable openings near the upper edge of the sheets of paper 18.

20 (Figs. 3, 4, 5 and 6) is a shaft mounted in the front part of the casing, and provided with a hand-wheel 21 by means of which it may be rotated. Mounted upon the shaft 20 are a pair of semi-cylindrical members and more particularly to a machine 22 having their faces roughencd in any suitable manner. VThis is preferably accomplished by coating their surfaces with a layer 23 of emery or similar material, the

objectv of this being to cause the Asurfaces ofV detail in Fig. 3. The dogs 25 are carried upon brackets 26, secured to the part 10 of the casing. To release the dogs 25 from the rack 24 at the proper timeduring the operation of the machine I provide 'the shaft 20 with a pair of cam wheels 27, each provided with a `cam face 28, adapted to strike against the inner endy of one of the dogs 25. The sheet 18 ,detached from the support 15 by means of the members 23 vis adapted to pass downwardly through a slot 29 formed in the bottom of the casing at the junction of the two parts 10iand 12. Toform a guide forthe sheets of paperv18 I turn up the edge 30 of the part 10.

rIn order to control the movement of the shaft 20 Iprovide a coin controlled mecha* nism, which will nowvbe briefly described'. Formed in the part 12 of the casing `is a coin chute 31, through which a coinfor controlling` the operation Vof the device is dropped. The coin after passing through the chute 31 enters a short movable chute 32 carried upon a lever 33 pivoted to a bracket 34 at 35 and projecting forwardly through a slot 36. (Fig. 1.) A projection 34a carried by the bracket 34 projects below the end of the chute 32 when in its normal position. The upper part of the bracket 34 has pivoted to it a lever 37, having a lateral projection 38 and a downward projectingl pin 39. The projection 38 is adapted to be engaged by coins of one size, while smaller sized coins engage with the downwardly projectingpins 39. The outer end of the lever 37 is adapted when in its normal position to be engaged with an arm40 carried by a wheel 41, mounted upon the shaft 20. This wheel 41 also carries a number of fingers 42 adapted to engage with a star-wheel 43, mounted upon the vshaft 44 of a counting device 45. The lever 37 is provided at its end with a pair of notches 46 (Fig. 3) which are adapted to engage with the edge of a disk 47, mounted upon the -sliaft20 and provided with 'a cut-away portion 48. The lever 37 also carries a bracket 49 adapted to bear kagainst the starwheel 43 and thus t move 1t against the tension of a coil spring 50 surrounding the shaft 44 ofthe counting device 45. 51 represents a fixed coin chute arranged belowfthe coin chute 32 and adapted to convey the coins into the cash boX 52, situated in the lower part of portion 12 of the casing. 53 is a spring attached at one end to the lever 33, hereinbefore referred to, and at the other end to a pin 54 carried by the casing 12. In order' to prevent the backward rotationy of the shaft 2O I secure to said shaft a ratchet wheel 55, engaged bya pawl 56, as shown in F ig. 5.

The operation of my device is las follows: The parts being in the position shown in Fig. 5 of the drawings, the forward layer of paper 18 will beheldagainst the roughened surface 23 ofthe semi-cylindricalmember 22 by the action of the coil spring 17, as the dogs25 are moved out of engagement with the racks 24, by the action of the cams 28 onthecam wheels 27. It will, however, be impossible to rotate the handswheel 21, becausethe stop is in engagement with the end ofthe lever 37. If, however, the coin be dropped into the shaft 31 ittwill rest upon the projection 36, and whenthe outer end of the lever 33 is moved toward the right the saidcoin will strike against either the projection 38 or 39, thuskmoving the front end of the lever 33 toward the right. This will cause the rear end of the said lever 33 to move toward the left out ofthe path of the stop 40, so that the hand wheel 21, and consequently the shaft 20, may be rotated. The

movement will be sulicient to bring one of the slots 46finto position toV be engaged by the periphery of the disk 47, so that after the movement of the shaft 2O is begun the lever 37 will be held in position until the rotation of the shaft 20 is complete. As' soon as the lever 33 is released the coin will fall down into the coin chute 51. As the shaft 20 is rotated the friction of the roughened faces 23 of the members 22 on the upper sheet of paper 18 will tear it from its pins 19 and convey it down through the slot 29. After half av revolution of the shaft 20 is completed the hubs of the parts 22 will be heldjout of contact with the sheet of paper 18 as the holder 15 is locked against forward movement by the engagement of the dogs 25 with the racks 26,`which engagement will take place shortly after the first movement of the shaft 20-on account of theA cams 28 movingrout of engagement with the dogs 25. As soon as the member 23 moves out of engagement with thesheet of paper 18, the sheet drops down through the slot 29, and if itv does not drop out of the machine by its ownweight it can be-readily graspedfbythe hand and withdrawn, as there is now nothf ing to retain it in the machine. pon'completing the revolution of the shaft 2O the parts are again brought into their normal position and the machine is again ready for operation.

Having fully described my invention, what I claim asnew and-desire to secure by Letters Patent of the United Statesis:
